I've had this Nissan R390 in partially completed form for some time. I just did not have a chassis to put it on. That changed last week. The chassis is a Scholer with custom side pans. All that it needs now is a custom front pan. Maybe tomorrow. Below are some images of the progress to date.

More progress

First, I fabricated a custom guide tongue. The stock unit was not long enough to allow the flag to sit close enough to the front of the car. Second, I fabricated and mounted a custom front pan. See images below for the mods.

I weighed the car in its present form (without glass, front headlight panel and interior). It weighed in at about 245 grams. I then tested the car with a very old and slow Hawk motor. The Nissan could just about break the five second barrier. However, the handling was great. I should have a new Hawk in a week or so and test again

I compared the R390 weight to my Camel Porsche 962. The 962 is also about 245 grams in racing form. The 962 is the record holder in terms of fast laps with 4.743 seconds.

Next steps

• Install new Hawk 7 motor and test car in finished form with glass, interior, etc.
• Fabricate a "short" front pan to reduce weight and test with finished body
• Test the car with no front pan.
• Determine which configuration works best.

All that is left is to clear, install new motor and interior

Below are images of the final product. The Hawk motors are set for delivery sometime in the next week or so. At that time, I'll post some performance figures

Finally got the Hawk motor broken in at low power, installed and tested. I was happy with the performance. The car was able to turn 4.83. (The class record holder is at 4.743). I still have a couple of things I will do. First, the motor cooling hole should be opened up a bit to allow for full are circulation. Second, I may try a smaller front pan - not sure of this because the car handles so well with the larger pan.

The car should get a bit quicker as the brushes seat fully.

Time to race! The next Triathlon at Electron Raceway will feature GT1, Trans-Am and Sports Cars. Tentative date for the race is 3/15. I intend to run the R390. Stay tuned for results. Just finished the wheel inserts. Below is an image
